Does this actually work? Shouldn't enable/disable_if depend on some
template arguments of f (and f is not templated here)?
Right.  Never mind.  We'll have to wait for concepts.
Ok.  Here's a method that actually works

template<bool is_static, class Derived>
struct base;

template<class Derived>
struct base<true, Derived> {
    static R f();
};

template<class Derived>
struct base<false, Derived> {
    R f();
};

template<class T>
class C : base<f_is_static<T>::value, C<T> > {};

In Christ,
